Review EDELBROCK Aluminum Intake Ro7 Raw Arca Nascar Truck Xfinity Chevy

The Edelbrock 28789 Performer RPM Air Gap Intake for Chevy applications is a high-performance intake system designed for race cars, specifically those competing in ARCA Nascar series and similar racing leagues. This intake system is engineered to deliver increased power and torque by improving airflow and providing better engine breathing.

The intake manifold is constructed of aluminum, a lightweight material that reduces overall engine weight. It features a large, open plenum design that facilitates the smooth and unobstructed flow of air into the engine. The RPM (Raised Port Manifold) design ensures optimal fuel delivery to the cylinders by aligning the runners with the valves for a straight shot.

The intake system includes a 750-cfm (cubic feet per minute) carburetor and an air gap design, which allows the carburetor to sit at a greater height above the intake manifold. This results in cooler air entering the engine, as the air is drawn from a higher position where it is denser and cooler.

This intake system is designed specifically for Chevy engines with 283, 289, or 302 cubic inch displacements. The raw, unfinished version of the intake (as indicated by the "RAW" in the part number) allows racers and engine builders to customize the intake to their specific needs, such as adding fuel injectors or customizing the intake ports.

The Edelbrock Performer RPM Air Gap Intake is a high-quality, race-proven intake system that delivers significant power gains and is a popular choice among race teams and engine builders. Its durable construction, efficient design, and customizable features make it a top choice for those seeking maximum performance from their Chevy race engine.

The Edelbrock 28789 intake manifold is a popular choice for Chevy racing applications, specifically in ARCA Nascar Xfinity Series. Here are some pros and cons that might help you make an informed decision about purchasing this intake manifold.

1. Designed for high-performance: This intake manifold is specifically designed for racing applications, which means it offers improved airflow and better power delivery compared to stock intake manifolds.

2. Raw cast aluminum construction: The raw cast aluminum construction allows for easy porting and flow bench tuning, making it ideal for race applications where every little detail matters.

3. Compatibility: This intake manifold is compatible with various Chevy engines, including small-block Chevy engines commonly used in racing applications.

4. ARCA Nascar Xfinity Series approved: This intake manifold is approved for use in the ARCA Nascar Xfinity Series, making it a popular choice among racing teams.

1. Requires additional work: As a raw cast intake manifold, it requires additional work, such as porting and flow bench tuning, to optimize its performance, which can add to the cost and time of the project.

2. Not street legal: This intake manifold is designed specifically for racing applications and is not suitable for use on the street.

3. Cost: Compared to stock intake manifolds or aftermarket intakes designed for street use, this intake manifold is more expensive due to its racing-specific design and raw cast construction.

In conclusion, the Edelbrock 28789 intake manifold is a high-performance intake solution designed specifically for racing applications. Its raw cast aluminum construction, compatibility with various Chevy engines, and ARCA Nascar Xfinity Series approval make it a popular choice among racing teams. However, its requirement for additional work, lack of street legality, and higher cost may make it less suitable for those looking for a more straightforward intake solution.

If you're in the market for a high-performance intake manifold for a racing application and are willing to put in the extra work, then the Edelbrock 28789 intake manifold may be a good investment for you. However, if you're looking for a more straightforward and cost-effective solution, you may want to consider other options. Ultimately, the decision depends on your specific needs, budget, and level of expertise.
